Multiple exposure sources and occupational fatigue profiles among healthcare workers: a cross-sectional latent profile analysis.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Occupational fatigue is a complex and widespread issue among healthcare workers, yet its heterogeneous manifestations remain inadequately studied. This study aimed to identify distinct fatigue profiles and examine the multifaceted determinants that differentiate these profiles. Methods: A cross-sectional survey was conducted among 734 healthcare workers. The assessment was conducted using the newly developed Healthcare Worker Occupational Fatigue Scale that has undergone reliability and validity tests. Latent profile analysis was used to identify occupational fatigue subgroups, and multiple logistic regression analysis was conducted to explore the influencing factors of each subgroup. Results: Latent profile analysis identified four distinguishable occupational fatigue subgroups: the compensated group (17.97%), the prodromal-symptomatic group (35.29%), the decompensated diffuse group (37.87%), and the systemic crisis group (8.86%). Multivariate logistic regression analysis revealed that perceived workload, department affiliation, number of night shifts per month, low intention to stay, noisy environment, commuting time, and individual-level factors, including gender and health status, were significant risk factors for occupational fatigue. Conclusion: Occupational fatigue among healthcare workers exhibits substantial heterogeneity and can be categorized into four distinct profiles, with multiple contributing factors. It is necessary to adopt hierarchical and personalized intervention strategies based on precise subgroup characteristics, such as systematically reducing the workload and optimizing the acoustic environment for the severe fatigue group, in order to effectively alleviate the occupational fatigue of healthcare workers.
